I'm a little unclear here. Wouldn't over-exposing just push the range of
steps down (numerically speaking) but not effect the tonal range? Does it
react nonlinearly to the light source? Or am I malinformed?

Why the water? I haven't begun playing with extra water - you mean yet
another variable... oh no!

A quick note as well - yesterday I sized a few different papers, one being a

my current style/materials - anyone out there using it?

See ya,
Adam
